After undergoing more change than any Super Bowl champion in recent memory, the Ravens will offer a glimpse of their revamped roster in their preseason opener against the Tampa Bay Buccaneers on Thursday.

The contest will offer little more than a cameo appearance for players expected to make the biggest impact in the 2013 season but will also provide welcome change for a group of players tired of working against one another after two weeks of practices in Owings Mills. Sunday’s practice at the Naval Academy in Annapolis provided a much-needed change of scenery, but a trip to Tampa will bring live-game action to a team with high expectations but also a number of veteran newcomers and rookies expected to contribute immediately.

The outcome of the preseason opener won’t determine answers for any of a number of questions facing the Ravens on both sides of the football, but the game will sharpen the focus of preparation for both coaches and players after facing competition in another uniform.

“They really are tired of seeing each other,” said coach John Harbaugh about the monotony of the first couple weeks of camp. “You can’t tackle to the ground, and you have to take care of one another. The game is a little bit different. The game is the game, and we’ll learn a lot. We’ll have a chance to move forward from there because there will be some things we’re expecting to see that we’ll see. But there will be other things that we’ll be surprised about – good and bad – and we’ll have to build off those things.”

Thursday will mark the first preseason meeting between Baltimore and Tampa Bay, but the teams have split the regular-season series, 2-2. Their last meeting came at M&T Bank Stadium in 2010 when the Ravens won 17-10 en route to a 12-4 season that resulted in the third straight trip to the playoffs for a Harbaugh-coached team. The Ravens haven’t played a game at Raymond James Stadium since the 2006 season opener and, of course, won the first of their two Super Bowl titles in Tampa on Jan. 28, 2001.

The Ravens are 40-27 all-time in the preseason and 13-7 in the Harbaugh era. Baltimore has also won 12 of its last 16 preseason games and is 19-14 in preseason road games.

Unofficial (and largely speculative) injury report

The Ravens are not required to release an injury report like they do for regular-season games, but I’ve offered my best guess on what the injury report would look like if one were to be released.

Most of the players ruled to be out will come as no surprise, but the status of a few will be in question. This list, of course, will not include any veterans who may be held out of the preseason opener due to the coaching staff’s preference. Cornerback Lardarius Webb is not expected to play as he continues to be held out of most 11-on-11 sessions during practices while working his way back to 100 percent following last October’s ACL injury.

I’ve been as skeptical as anyone about the offseason praise bestowed on the second-year Florida product, but Thompson has looked increasingly comfortable working in the Ravens’ starting offense over the last week, whether it’s lining up in the slot or on the outside while Tandon Doss works inside in certain three-wide sets. Quarterback Joe Flacco complimented Thompson’s ability to work inside while also possessing unique speed for the slot position.

It will be interesting to see how offensive coordinator Jim Caldwell uses Thompson in the slot as he provides a speed element that neither Anquan Boldin nor Dennis Pitta possessed, but the biggest questions will be whether the former rookie free agent can catch the football consistently — the knock on him during his collegiate career — and whether he’s strong enough to create separation against press coverage. However, Thompson has performed well enough in the spring and summer to warrant extended looks in the preseason.

2. DE Chris Canty

The signings of pash-rush specialist Elvis Dumervil and free safety Michael Huff garnered more attention in the offseason, but Canty will provide the Ravens with a prototypical 5-technique defensive end (lining up over the outside shoulder of the offensive tackle), an asset they sorely lacked last season following the free-agent departure of Cory Redding. Arthur Jones was better suited to play inside and Pernell McPhee battled injuries throughout the year, forcing a banged-up Haloti Ngata to move away from his ideal spot and play outside more often. As a result, the defensive line suffered mightily against the run and getting after the quarterback.

Canty’s unique combination of size, power, and arm length — he’s listed at 6-foot-7 and 317 pounds — is exactly what you’re looking for to hold up against offensive tackles at the point of attack in the running game as well as to get after the quarterback a bit and put hands up to disrupt passing lanes. If Canty can remain healthy, his dirty work upfront won’t always show up in the box score but will be as valuable as Dumervil’s ability to bring down the quarterback and Huff’s work in the secondary.

3. LB Josh Bynes

Veteran Daryl Smith appears to be the overwhelming favorite to man the Mike inside linebacker position, but Bynes is battling Albert McClellan and second-round rookie Arthur Brown for the Will spot with most attention being paid to the Kansas State product for obvious reasons. However, Bynes has taken a large majority of the reps with the starting defense while Brown has primarily worked in sub packages and with the second-team unit.

Bynes missed nearly all of last year’s training camp with a back injury but eventually worked his way back to become a valuable special-teams contributor and filled in admirably after a number of injuries at the inside linebacker position late in the season. He has been complimented by coaches for having a good mind for the game and is strong against the run, making him the early favorite to start over the undersized and inexperienced Brown, who will likely replacing Bynes in passing situations to utilize his pass-coverage ability.

4. C A.Q. Shipley

Shipley’s 6-foot-1, 308-pound frame doesn’t impress you, but his work at the center position has earned him plenty of reps with the starting offense in a close battle with 2012 fourth-round pick Gino Gradkowski. I’ve maintained all spring and summer that Gradkowski was the favorite, but it appears that Shipley has closed the gap over the first couple weeks of training camp.

The Penn State product graded out well in his first real opportunity to play in the NFL last year with Indianapolis, but neither Shipley nor Gradkowski has great size, making you wonder if either will hold up physically against bigger opposing defensive tackles during the regular season. This might be the closest position battle of any for the Ravens this summer.

5. WR Marlon Brown

If you’re looking for this year’s rookie free agent to come out of nowhere in the way that past individuals such as Thompson or LaQuan Williams or Dannell Ellerbe did, Brown is an intriguing candidate because of his 6-foot-4 frame. His final season at the University of Georgia was cut short due to a torn ACL, which limited his ability to work out for teams during the draft process and contributed to him going undrafted.

Brown doesn’t possess overwhelming speed, but he’s shown a consistent ability to catch the football in practices unlike 2012 sixth-round pick and fellow big target Tommy Streeter, who is clearly behind Brown and seventh-round rookie Aaron Mellette on the depth chart. If Brown can shine while working with Tyrod Taylor and the second-team offense over the first couple preseason games, he could find himself at least in the conversation for a roster spot, especially with the Ravens desperately looking for red-zone targets in the passing game following the season-ending injury to Pitta.
